MATRlx-MAKI-Nc MACHINE.

'SPECIFICATION forming part of Letters Patent No. 530,279, datedDecember 4,1894. Application filed December 27. 1892. Renewed May 1,1894. Serial' No. 509,719. (No model.)

To' all whom it `may concern:

Be it known that I, MARCUS LANE, a citizen of the United States,residing at Freeport, in the county of Stephenson and State of Illi,-nois, have invented a new and useful Improvement in Matrix-MakingMachines; of which the following is a specification. i n n Y Myinvention relates to improvements `in a type-writing or matrix makingmachine, in which type characters, in relief, upon pivotal type-bars areactuated from a key-board to imprint uniformly in a certain fixed tieldacross which the material to receive the characters is caused to travel.i

`My object is to provide a machine of an improved construction of theclass named to be used either as atypewrit-er, or in making matricesupon a bed of plastic material, which material, when `allowed to harden,may aord a surface provided with a mold or intagliomatrix of eachcharacter impressed so that a tereotype platemay be cast or moldedthererom.

While, as before stated, my machine is adapted for either typewriting ormatrix making, the machine shown in the drawings is intended Inoreparticularly for the latter purpose, and for that reason the descriptionis confined to a matrix making machine. With slight substitution ofdetails hereinafter pointed out the machine may be adapted fortypewriting.

Referring to the drawings-Figure l is a partly broken and partlysectional -plan view of my improved machine; Fig. 2, alongitudinalcentral section of the 4same taken on line 2 of Fig. 1 andviewed in the direction of the arrow; Fig. 3, an enlarged section takenon line 3 of Fig. 1 in the direction of the arrow; Fig. 4, a sectionalplanview Ataken on line 4 of Fig. 3; Fig. 5, a broken view illustratinga bearing detail of the construction; Fig. 6, a broken perspective viewof one of the details of the spacing mechanism, the view showing twoadjacent differential spacing plates, separated toillustrate `theirconstruction; Figs. 7 and 8, enlarged broken sectional v views ofportions of the spacing mechanism,

A is the stationary part or frame of the machine comprising a base Asides A2 A3, keyboard platform A4, shelf A5, top-board .A6 andback-board A7.

K represents thekeys, or properly the keyboard of the machine.

For the purpose of illustration and to prevent confusion the key-boardis shown in the drawings to be provided with forty type operating keys,divided into two sets of twenty each located respectively at oppositesides of a set of central keys, provided for spacing purposes.` One typekey is provided for each type, and the type'` may be more or less innumber than is shown. In practice I prefer to provide eighty-four typebarsand characters and eight space keys, the latter being the numbershown upon the key-board in Fig. 1.

Presuming that the `type to be employed in this machine is what is`known in the art as ten point long primer of eight units to the picaem, I prefer to provide the key-board'as follows: Keys of typeofthesameequivalence in units are located together, and at the sides of thespace keys of the same number of ICC units. In the key board shown thefirst line marked t t contains keys of type of two units. The half ofthe next line marked t contains keys of type of three units. The otherhalf of the same line, and all of the next line, both designated by thesmall letter t2, are the keys of type of four units. The next line'marked t3 contains keys of type of five units. The half of the next linemarked t4 contains the keys of type of six units, and the other half ofthe line, marked t5, contains the keys of type of seven units.

s is aspace key of one unit; s,a space key of two units, the equivalentof the type keys in the line t; s2, a space key of three units; 33s,space keys of fourunits; s4, a s-pace key of ive units; S5, a spacekeyof six units, and sthe space key of seven units,-all the space keyscorresponding in units with the lines of typekeys with which they areplaced adjacent.

Each key comprises a head i" upon a stem r', and each stem passesthrough a separate key lever r2, which is pivoted to a bearing r3suspended from the top board A, At its rear end each lever r2 ispivotally connected to a lever r4 which between its ends is pivoted tothe main frame.

Each type or die B is preferably of steel and secured in the end of atype-holder B pivotally mounted between its ends upon a type-bar B2,which near its opposite end is pivoted to the main frame at T5. At theend of its short arm each type bar is pivotally connected by means of alink r6 to the end of one of the levers r4.' In the top-board A6 of themain frame is a semi-circular opening 0c, and

the type bars are pivoted in the bearings T5, arranged around thesemi-circular edge of the opening m. Near the opening @c is a cushionedrail 0c against which the type bars. rest when in normal position, asindicated in Fig. 2. The type bars extend radiallyfrom an opening y, atthe center of the arc described byy the semi-circular edge of theopening x, and when swung upon their pivots rs the type holders strikeinto the opening y. The opening y is in a yielding stop, or typereceiving lever q, which is pivoted at q to the under side of the boardA6 and projects beyond the edge of the opening The lever g is heldbetween its ends normally against the under surface of the top-board A6by a confined spring q2.

When a key is struck the head v' is depressed With its lever r2, causingthe latter to swing upon its pivot r3, swing the lever r4, and draw downthe link r6 to swing the type bar and type holder in the direction ofthe dotted circle in Fig. 2, causing the type-holder to strike into theopening y of the type receiving lever q.

The material which receives the impression of the type and aords thematrix is preferably a plastic substance capable in a comparativelyshort time of becoming very hard from exposure; or it maybeacomparatively hard substance capable ofreadily receiving anindentation, and of hardening still further under the action of heat orother agency.

The material X which is to receive the indentations is spread orotherwise inserted in a matrix holder p, and must afford a smooth plainsurface. The matrix holder' p may be a metal plate, of the form in crosssection shown in Figs. 2 and 18, removably secured upon a movablecarrier bed 0 provid ed on its under side with guide projections oadapted to surround and slide upon horizontal guide rodso2 extendinglongitudinally of the machine. 'lhe guide rods ozare upon a slidingframe 03 provided, at opposite ends of its rear edge, with guideopenings 04 of smooth bore to slide upon a guide rod o5 mounted upon theplatform A5 of the machine. Near its forward edge the frame o3 isprovided with internally threaded guides o6 adapted to receive a wormshaft o7 held against longitudinal movement in bearings o8 at oppositeends of the platform A5, as shown most clearly in Fig. 16. At one end ofthe worm shaft 07, beyond its bearing 08, is a hand-Wheel o9, by meansof which the worm shaft may be turned to cause the sliding frame o3 tomove in either direction transversely of the machine.

On the top-board Ai is a casing C in which is housed a spring actuatedtrain of gear wheels or clock gear; the spring being upon an arbor z, tobe wound up by a suitable key, and the final wheel of the gear being adisk C on the outer side of the case. The train of spring actuated gearsis notillustrated in detail for the reason -that it is of commonconstruction. Its function is simply to give to the disk C a progressivemovement on its axis whenever it is' released, as hereinafter'described. On opposite sides of the disk C',

and in the relative positions shown in Figs. 9 and l0, are pins n n',the pins n being on the outer side of the disk, and the pins n on theinner side thereof.

Pivoted to the side of the case C above and to one side of the disk C isa swinging arm n2 formed on its forward edge with a cam surface n3terminating at an abrupt shoulder n4. At its lower end the swinging arm'n.2 is provided with a longitudinal slot n.5 through which it ispivotally connected, by means of a pin 17.6, to an oscillating andlongitudinally reciprocatingdepressing lever a7. The depressing levern.7 is provided at its rear end portion with a longitudinally extendingslot ns through which passes a pin W9, fastening the lever pivotally tothe side of the case without interfering with its longitudinalreciprocation. Fastened at one end to a pin n10 on the side of the caseand at its opposite end to a lug n on the lever pr1.7 is a spring i112,which tends normally to draw thev lever a7 forward. Confined andreciprocated in a guide als, on the side of the case C, is a plungernMrprovided at its lower end with a head als'. The lever a7 is maintainednormally raised to the IOO lIO

top of the slot a5, in the arm n2, by a finger l spring n, and theplunger rests at its head n.15 normally upon the upper side of the levernl. The upper end ofthe plunger n is formed with a cam surface fn.Fastened at its upper end upon the rear side of the plunger nu andpivotally connected at its lower end to the receiving lever q is a rodp18. When the mechanism described is in its normal position the lowestpin n, on the diskC'-, bears upon the cam n3 adjacent to the abruptshoulder n4; andthe lowest pin n bears against the `side of the plunger'n14 adjacent to the cam surface nl?. At its forward end portion thedepress-V ing lever nl is provided with an impact face w19. In practicethe face um extends in aplane about one hundredth part of an inch belowthe lower edge of the lever nl; but in the drawings (Figs. 9 and 10) itis somewhat exagger-` ated for the purpose of illustration. a Below theimpact face ntwhen the lever is in its normal position, is a stop w20 inthe form of a pin projecting from the side of the case C.

The object of the mechanism described is to regulate with absolutecertainty the depth of the impressions made by the typeupon the surfaceof the matrix material.

Each type-holder B', as before stated, is pivoted between its ends uponthe end of its type bar B2, and it is held normally by a spring T7 inthe position to cause its free end, containing the type, to strike intothe openingy of the receiving lever. On each type-holder adjacent to itspivot is au annular shoulder rs below which theitype-holder is ofreduced diameter, as shown. 'lhe reduced portion of the type-holdermoves readily through the opening y, but its movement is stopped by theengagement of the shoulder r3 with the surface ofthe receiving lever qabout the opening y. In its movement from the rail fr to the opening ythe endof the type-holder de-4 scribes a circle, as before stated, ofwhich its bearing T5 is the center, but in moving downward in theopenings y the type-holder must` extendin a plane perpendicular to thesurface of the matrix material. After entering the opening y thetype-holder is guided by the opening to move in a vertical plane, at atangent to the circle described in its previous movement, and in doingthis the type-holder turns upon its pivot against the resistance of thespring r7. On the upper end of the typeholder is an adjustable set screwr9, for a purpose hereinafter described. a

In operation when a type-key is struck the respective type lever B2carries its type-holder to the opening y, causing the lower part of theholder to pass through the said opening until the shoulder rsistrikesthe receiving lever. The impact of the shoulder against the receivinglever depresses the latter, against the resistance of the spring q2, anddraws down the rod n.18, and, with the latter, the plunger n and levernl, against the resistance of the spring nw.` The downward movement ofthe plunger 'n.14 releases the `pin n', engaging the plunger, andpermits the disk C', to be revolved by the spring-actuated gear housedin the case C. The pin n at the cam 'n3 is moved to release the arm n2,causing the depressing lever p7 to plunge forward under the action ofits spring n12 over the top of the set screw r,- and the passage of thepin n across the cam surface n depresses the plunger rtl4, a certainpredetermined distance, to press the impact face 'n.19 of the lever nlupon the set screw Maud thus force down the type-holder to press` thetype into the sistance of the spring nu, until the disk U is stopped bythe engagement of the next pin n with the side of the plunger nl# Beloweach operating lever r2 forward of` its pivot r? is a spring rw (Fig.v2) which bears against `the lever r2 and operates, when the key isreleased, to raise the lever to its normal position.

u The action of the mechanism which regulates the depth of theimpression made upon the matrix material is very quick, so that whenvthe operator releasesthe key last struck the type-holder willhave beenreleased and thrown upward by the depressing lever, and the type-bar andtype lever swung back to their initial positions by the IOO action,primarily, of the spring q2 and secondarily` by thatof the spring rw.

d It is-desirable inmatrix making that there shall be aslittledisplacement as possible of matrix material, around the intaglio,under theimpact of the type in making impressions, and it is found inpractice that less displace` ment of material occurs when the impressionis made by repeated and comparativelygentle impacts than under a singlestrong impact of the type. The link and lever connections between theoperating levers rzand type-bars B2 are such that whenv a key isdepressed the type-holder is swung with a greater force than 'isconsidered desirable in ordinary typewriting machines,owing to theirconstruction, and a without any greater exertion of force by theoperator. This is particularly desirable for manifolding. l

` When the shoulder rs strikes the receiving lever q it springs thelatter downward until the impact face/rt19 of the lever a7 strikes thestop n.20. This permits the type in practice to enter the matrixmaterial a distance approximating say one-hundredth part of an inch.Farther than this, therefore, the type will not enter the matrixmaterial underl the direct force exerted from the key. To engage the topof the type-holder the `impact face nm passes beyond the stop 01,20, andthe second impact exerted under the action of the spring mechanismhoused in the casing C,

forces the type Asay one-ftieth yof an inch into the matrix materialmaking a total depth of impressions of about one-thirty-third of aninch, which is regarded as sufficient. The depth of impressions underthe impacts stated may be varied if desired by raising or lowering theframe carrying the matrix material, adjusting the set screws r9, orincreasing or diminishing the extent of projection of the impact facen.19. When the device is used as a typewriter it may be regulated ineither way described to meet the requirements of manifolding when thetypewriter is used for that purpose.

The matrix bed p, as before stated, is mounted upon a bed-plate arrangedto travel upon the guide-rods 02, in a direction longitudinally of themachine, and the bed-frame is mounted to travelin the directiontransversely `of the machine by turning the worm rod o7. Each time animpression is made upon its surface the matrix material must travel asufcient distance below the openingy to present a new surface of theextent desired for the next impression; and the movement of the matrixbed for this purpose is accomplished by the mechanism now to bedescribed. Bearing against the rear edge ofthe bed-frame o is a rod o10movable longitudinally through guides 011011 (Fig. 2) upon a bracket 012extending from the rear of the machine. Journaled in the bracket 012 isasheave 013. A cord 014 secured at one end to the under side of theplatform A5, extends over the sh eave 013 and is fastened at itsopposite end to the free end of the rod 010. Between the platform A5 andsheave o13 the cord carries a weight 015 which is suspended upon apulley 016 running on the cord. The action of the weight 015 is to drawthe rod o10 forward and through the latter to move the bed-frame o inthe forward direction. If desired a suitable spring may be employed, asthe recognized equivalent of a weight, to advance the rod 010. The rod010 presses against the rear side of the bed-frame, and to permit thelatter to be moved transversely of the machine without strain upon therod, the rod 010 carries wheels 017 which engage the rear side of thebedframe 0 and permit the latter to character is struck, and animpression made upon the matrix material, the bedframe must be moved adistance equal to the space occupied by the character, and the spacebetween characters, ywhich in all cases between the letters forming aword will be the same. The characters in a font of type are each made tooccupy a certain number of units of space;

`that is to say the narrowest characters occupy two units, and thewidest characters, provided for in the machine shown, occupy seven unitsof space, the units in the present instance' being one-eighth of a picaem or oneforty-eighth of an inch. Therefore, each time a letter orcharacter in the first line t of the key-board is struck the bed-framemust move a distance equal to two units to bring a fresh surface of thematrix material below the opening y in which the next character may beimpressed, the distance being increased to three units when keys t arestruck, and so on.

Each type-holder B is provided with a socket Z capable of receiving thetype of the character of largest number of units in the font. One sideof the socket is a straight wall or surface Z against which the typemust be set irrespective 0f its Width. Entering the said socket from theopposite side of the typeholder are set screws Z2, which operate totighten the type in place and maintain it in contact with the saidsurface, or registering wall, of the socket Z. The type being placedagainst the registering walls of the type-holders, the sockets of all ofwhich are the same, the, initial point or line of each letter willstrike upon the same point, in the matrix material, with relation to theopening y; and the forward or initial point of each intaglio will thusbe at the initial point or line of the first unit of space in the fieldbelow the said opening. As each character, in order to make an uprightintaglio, must extend at a different angle to its radial type bar, Imake the type-holders in two sections Z3 Z4, the upper section Z3, whichis pivoted to the typebar, having a socket Z5 in its under-surface toreceive the upper reduced end Z6 of the lower section Z4. The lowersection contains the type, and it may be turned axiallyin the socket Z5to adjust the type to any desired angle with relation to the type-bar,and when adjusted it may be tightened by a set-screw Z7. Thus all thetype-holders may be constructed alike.

Extending below each transverse line of keys of the same equivalence onthe keyboard, is a swinging spacer-plate Zo mounted at its rear edgeupon a shaft Zo which is pivoted in bearings on the under side of thekey board platform. Below the spacer plates k and toward opposite endsof the latter are two stationary and longitudinally extending strips orarms k2 provided in their upper edges with serrations affording inclinesk3. The topmost point of each incline is directly below a shaft k', andeach plate k is adapted to swing upon its pivots down in the directionof the coincident inclined edges of the arms 7a2. The plates Zr. belowthe spacer key s, and full lines t t2 and t3 of character keys, arepivoted in bearings 104 (see Fig. near opposite edges of the under sideof the key-board platform. Under the line t t2 I and line t4 t5 thespacing plates are divided at points between the spacer keys s2 s3 andS5 s6, respectively, where bearings 7a4 are provided in proper positionto receive the adjacent ends of the shafts. (See Fig. 15.) At theinclined edges k3 are bracket pieces las, having threaded openingscontaining set screws k6 against the tops of which the spacing platesare adapted to strike. The set screws may be adjusted to limit thedistance to which the free ends of the spacing plates may be swung inthe downward direction. Each shaft k is provided with a downwardextending arm k12, (sce Fig. 8,) and connected at opposite endsrespectively with the arm k12 and side of `a stationary part of themachine, is a spring k7 operating normally to maintain the free edgesofthe plates k against the lower ends of the stems r of the keys. 0neach plate k (extending the full length` of a line of keys) is adownward extending projection los, which may be stiffened by a rib kg.At the lower end of each projection las is a backward extending toe la.All the projections ksarein one longitudinal line. The plates 7c whichextend below the half lines of character keys t2 and t5 (four and seven`units, respectively) are provided at their ends adjacent to their pivotsnear the center of the key-board with plates'la11 whichextend beyondtheends of the plates 7c. On the adjacent plates la, which extend below thelines t t4 of type` keys, are projections ks, like the projections ksabove described, and provided with similar toes k1". The plates k1?extend across the adjacent projections ks, as shown in Fig. 7.` Belowthe line of projections ks, and extending longi-` tudinally ofthemachine, is a spacing bar t provided in its upper` edge with notches orrecesses z" into which the said projections ks extend. The bar fi ismovable longitudinally through guides t2 on theframe ofthe Ina-` chine,and is held normally at the forward limit of its movement, with the rearedges of its recesses t" against the toes 1010, by a spring i3 attachedat one end to a downward extend-` ing portion 4 of the bar, and atitsopposite` ends to a part of the main frame, (Fig. 3.)

Journaled in the frame ,adjacent to the bart' is a ratchet wheel h, upona shaft h carrying apinion h2. The bearings of the shaft h are uponabifurcated standard A8 which between l its forks aords a vertical guidefor a block or spacing cam-frame D. The guide AS is formed with guiderecesses g, and upon opposite sides of the cam frame D, near its rearvertical edge, are guide projections gadapted to move in the guiderecesses g. On the forward edge of the frame D is a rack D', whichmeshes with the pinion h2 on the shaft h. The rear edge of the frame Dis made tapering to afford a cam D2. 4

Whenever a key is pressed down, its stem r bears upon a plate .c andswings the latter down upon its pivots causing the toe'klo, on itsprojection ks, to engage the spacing bar c' and move thelatter backwardagainst the rekeys, as describedfthe dog turns the ratchet wheel.` Theturning of the ratchet wheel turns the pinion h2, and by the engagementof the latter with the rack D moves the cam frame D in the verticaldirection. 'llhe different parts of the spacer mechanism are soconstructed, with relation to each other, that when the space keys isstruck down the plate k below the said key will be stopped, by the setscrews k6 below it, when it has swung a predetermined distance. Inswinging this distance the toe kw moves the bar t', against theresistance of the spring 3, j ust far enough to turn the ratchet wheel ha distance equal to one tooth of the ratchet, which in thepresentinstance is one-twelfth of au inch. The difference in diameters betweenthe wheel h and pinion h2 causes the latter when the ratchet Wheel ismoved one-twelfth of an inch to raise the rack D', and consequently theframe D,onetwentyfourth of an inch. The roller m on the bed plate o,which carries the matrix material, bears against the cam surface D2 ofthe frameD, being held thereto by the weight 01'5 before described. Thecam surface D2 is so constructed with relation to the block that in therise of the latterone-twentyfourth of an inch the movable bed frame ispermitted to move forward one-fortyeighth of an inch, that being oneunit measurement. The roller m prevents' the frame D from bcing retardedin its forward movement by the `pressure against it of thebed frame, andre- D. The set screws k6 below the space plates against which the stemsof the two unit keys strike, are sufficiently lower than those of thesingle unit spacer to permit the plate lc to turn twice the distance,andmove the bar t, ratchet wheel h, pinion h2 and block D twice thedistance, and permit the carriage to move a dis- -tance of two units.`The set screws lo@ under the three, four, ve, six and seven unit spacerplates are set proportionately lower, so that the bed frame will `bemoved three units under the action of a three unit key, and so on. Itwill thus be seen that as a key is struck the lcam frame will be raisedto permit the matrix bed frame to feed forward a distance equal to thenumber of units represented by the key. It is necessary, however, thatthe bed frame shall not move when released by the `cam surface D2 untilafter'a character 'has beenstruck and an intaglio made in the matrix. Toprevent this movement of the bed frame I provide stop mechanism, whichengages the underside of the traveling bed frame when, a key is moved inthe downward direction and holds the same until the key is` released. jj

The` frame, or cam-facedA stop, D, is progressively movable in the sensethat after it has been raised, when a keyis struck, it does not retract,but remains stationary until again advanced by the striking of a key.Thus it moves progressively one step at a time, the length of the stepin each operation being governed by the number of units of spacerepresented by the key struck, to stop the bed frame when the latter hasbeen advanced by its feed a corresponding number of space units.

Secured to the platform A5 is a bracketf having an upward and forwardextending arm j and a downward and forward extending arm f2; andadjacent to the bracketfis a forward and slightly downward extendingbracket e. The arm f2, of the bracket f, and the bracket e arebifurcated at their free ends (Fig. 2l) to afford the bearings e e2f3fLfor a rock shaftf5. On the shaftf5 between the bearings f3 f4 is an armf, and extending through a guide f7, at the top of the arm f', is avertically reciprocating plunger fs provided with a friction head fi. Alink flo is pivotally connected at opposite ends, respectively, to thelower end of the plunger f8 and to the free end of the arm f6. On thelink f1@ is a toe fu, which, in the turning of the shaft as hereinafterdescribed, limits the distance of the movement of the shaft, arm f6,link f10 and plunger in one direction. On the shaft f5 between thebearings e and e2 are an upward projecting lug es, having a laterallyprojecting pin c4, and a downward projecting lug e5. Extending downwardfrom the bearing e2 and forming a rigid portion of the bracket e is anarm e having a forward projecting finger e7 and laterally projectingfinger e8. Pivoted to the free end of the lug e5 is a rod e9 which worksthrough a guide opening e10 in the end of the finger es, asindicated bydotted lines in Fig. 3. Around the rod e9 and confined between the headof the rod, at the lug e5, and the finger e8 is a spring en. Pivoted atone end to the rear end of the rod i is a rod d provided at its free endwith a curved hook or fin-ger d', a socket d2, an abrupt surface cl3 anda cam surface d4. The rod d normally engages at its socket d2 the pin e4on the lug e3; and a spring d5, connected at one end to the finger e7and at its opposite end to the rod d, tends to maintain the latter downin its normal position. When the bar 'i is moved backward,as beforedescribed, it moves the rod d, causing the abrupt surface d3 on thelatter to bear against the pin e4 and turn the lug c3 and the rock shaftf5 in the backward direction. This movement of the shaft f5 swings thelug c5 downward, reciprocates the rod e9 through the guide e10 andcompresses the spring en. The turning of the shaft f5 in the backwarddirection, therefore, is against the resistance of the spring e, Thebackward turning of the shaft f5 also turns the lug f6 in the backwarddirection, and causes the link f1 to raise the plunger f8 until the toef11 strikes the adjacent surface of the arm f of the bracket f. The headof the plunger is directly below the under surface of the matrix bedplate and when raised, as described, engages and holds the latter.

The operation of the machine is as follows: The matrix material X isplaced in the ma.- trix bed jp, the matrix having a smooth andpreferably polished upper surface. The matrix bed p is placed upon themovable bed frame o and secured thereon by means of the thumb screws X',shown, or other suitable means. The cam block D is forced down or raisedas may be required to bring the surface of the matrix material, at whichthe impressions are to start, below the opening y of the receivinglever. The keyof the first letter or character to be impressed upon thematrix surface is struck, causing the type-holder of that character tobe swung over t-o the receiving lever and strike the latter with itsshoulder rs to make an initial impression, as before described. Thestriking of the shoulder against the receiving lever releases thedepressing mechanism operated from the disk C', causing the type-holderto be engaged, depressed and released, all as before described. In themeantime, the respective spacing plate 7e will be turned by the stem rof the key to move the bar t', ratchet wheel h and pinion h2, as beforedescribed, to raise the cam block D the proper proportionate distancewith relation to the number of units of the character impressed. In thesame backward movement of the bart' the stop mechanism, described, isoperated. When the single unit space key is struck the rod d swings theshaft and plunger upward without producing disengagement. of the abruptsurface d3 with the pin e4. The backward movement of the rod, however,is double the distance when a two unit key is struck and treble thedistance when a three unit key is struck, and so on. When the key of aletter of more than one unit is struck the rod d is forced backward andthe shaft f5 swung until the toe f strikes the under surface of thearmf, as before described. The shaft can' turn no farther, and thesocket portion d2 of the rod disengages itself from the pin e4, and therod slides at its cam surface d4 along the pin, a distance dependingupon the distance to which the rod is moved under the action of the key,the extent of movement varying according to the number of unitsrepresented by the key. The engagement of the cam surface d4 with thepin e4 in the meantime prevents the shaft from returning to its initialposition to release the plunger or stop from the base of the matrix beduntil the key is released and the rod t' moves in the forward direction.The striking of a space key operates the spacing mechanism, asdescribed,'

and causes the bed frame to be moved a distance corresponding with thenumber of units represented by the space key.

at all times of the number' of units he may have left between the lastcharacter struck and the end of the line, I provide a dial orspace-indicator E in a conspicuous place upon the machine, preferablyabove the case C. The dial E is marked around-its edge with units, andupon a shaft c at the center of the dial is an indicator c whichregisters with the unit marks and indicates the relative position of thecharacter struck upon the lines. The shaft c is connected by speedreducing gearing with a drum c2. On `the shaft cis a clock spring c3which tends to maintain the indicator at the initial position upon thedial. A cord c4 is attached at one end tothe lower end of the cam frameD and extends thence Movement of the cam frame D in the upward directioncauses the cord c4 to be drawn in the direction of unwinding from thedrum to `turn the latter and, through the intermediate gear and shaft c,to turn the indicator.` The parts of the mechanism are so adjusted withrelationto each other that the rise of the cam frame under the action ofthe single unit spacer will cause the indicator to move one unit uponthe dial, the rise of the Vcam frame under the-action ofa two unit key,to move the indicator the distance of two units upon the dial, and soon. The operator being aware of the number of units in the line that heis printing, will be able to note, for the purpose of j ustiflcation, bythe position of the indicator upon the dial, the number of units whichhe may still count upon. When the first line is filled with charactersand it is desired to start a new line, the dog i5 is disengaged from theratchet wheel h and the operator by placing his hand upon the top of thecam frame D presses the latter down, thus causing the matrix bed to bemoved until it reaches its initial position,

which will be shown by the indicator .on the dial. Assuming, forexample, that-the line to be printed is upon a 12mo page having a widthof twenty-six pica ems or two hundred and eight units, the initialstarting point for every line will be at unit No. 208 on the dial.Before commencing a new line it is necessary that the carriage o3 uponwhich the matrix and matrix bed frame are mounted shall be movedtransversely of the machine to the left to bring a new surface for theline to be produced. If the lines are tobe ofthe distance apart which inthe art is known as 4 solid matter (that is to say not leaded) the ingwith the surface of the matrix-material;

and a typewriter ribbon `may be mounted in the usual way to move acrossthe lield in which the type strike.
